Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can form a so-called fully folded staircase that is bent in a U-shape with good quality and convenience without lowering the construction efficiency, and is particularly suitable for a house having a large staircase. Uru stairs device.

[0002]

2. Description of the Related Art U in a multi-storey apartment house
A so-called fully folded staircase that is bent in a letter shape may be provided. Conventionally, as shown in FIG.
A U-shaped stair frame structure a as schematically shown in Fig. 5 is integrally manufactured in advance in a factory, and after being carried to the site, the stair frame structure a is attached to a house frame structure such as a pillar by welding, or FIG. As shown in FIG. 3, the linear staircase bodies b1, b2, b3 and the surrounding staircase bodies c1, c2 are carried into the site in a divided state, and each member is attached to a house frame structure such as a pillar by welding. There were things such as forming a U-shaped staircase.

[0003]

However, in the case where the U-shaped stair frame structure a, which is integrally manufactured, is carried into the site, it is possible to efficiently form all the folded stairs by its mounting, but the construction site. When the area is narrow, the staircase frame structure a may be too large to enter the staircase. Particularly in the housing situation in recent years, in addition to the shortage of land, the housing is dense in the city, so that there are many narrow spaces, making it more and more difficult to carry the integrated stair frame structure a to the site.

On the other hand, in the case where the linear staircases b1 and b2 and the round staircase bodies c1 and c2 are divided and carried into the construction site, although the difficulty of carrying in due to the narrow land is solved,
Since the stair frame structure is subdivided, many welding points are generated when mounting the house frame structure, which lowers the construction efficiency, and if there is some variation in the construction quality, it also increases the cost. There was a problem such as inviting.

Therefore, without lowering the construction efficiency,
Further, there has been a strong demand for a stairway device having a novel structure that can be constructed even in a narrow area and that can form a staircase that bends in a U shape with good quality and at low cost.

The present invention is basically based on an intermediate staircase body and upper and lower staircase bodies, and is of a staircase device capable of forming a staircase that is bent in a U shape with good quality and convenience without lowering the construction efficiency. It is intended to be provided.

[0007]

In order to achieve the above-mentioned object, a staircase device of the present invention is a staircase device which is bent in a U shape, and is provided at the upper and lower ends of a linear staircase part. An intermediate staircase body integrally provided with a circular staircase portion having a horizontal and triangular step plate whose outer edge is inclined with respect to the center line, and upper and lower staircase bodies which are connected to the respective circular staircase portions at right angles to the intermediate staircase body. Consists of.

[0008]

The staircase device is composed of an intermediate staircase body in which turning staircase portions are integrally provided at both upper and lower ends of a linear stairway portion, and upper and lower staircase bodies which are connected to the turning staircase portion at a right angle. Since it is divided into the intermediate staircase body and the surrounding staircase portion in this way, it is possible to carry it in even if the construction site is narrow.

Further, since the so-called all-fold staircase that is bent in a U shape can be formed by connecting the intermediate staircase body and the turning staircase portion, the number of joints can be reduced, and the construction efficiency can be improved and the construction can be performed. It is possible to prevent variations in quality, provide stairs with good assembly accuracy, and increase the efficiency of transportation to the construction site and reduce costs because the members for stair formation are not subdivided more than necessary. Also useful for.

Since such a staircase device expands the site area, it can be suitably used in a house having a large staircase, and, for example, the intermediate staircase and the rotating staircase are connected by bolts. By doing so, the welding work can be reduced, and the workability and the economical efficiency can be further improved.
